iOS调用系统的发短信功能可以分为两种：1，程序外调用系统发短信。2，程序内调用系统发短信。第二种的好处是用户发短信之后还可以回到app。这对app来说非常重要。
###程序外调用系统发短信
这个方法其实很简单，直接调用openURL即可：
[[UIApplication sharedApplication]openURL:[NSURL URLWithString:@"sms://13888888888"]];
###程序内调用系统发短信
#####1）导入MessageUI.framework，并引入头文件：
#import <MessageUI/MessageUI.h>
#####2）实现代理方法MFMessageComposeViewControllerDelegate
-(void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
[self dismissViewControllerAnimated:YES completion:nil];
switch (result) {
case MessageComposeResultSent:
//信息传送成功
break;
case MessageComposeResultFailed:
//信息传送失败
break;
case MessageComposeResultCancelled:
//信息被用户取消传送
break;
default:
break;
}
}
#####3）发送短信
-(void)showMessageView:(NSArray *)phones title:(NSString *)title body:(NSString *)body
{
if( [MFMessageComposeViewController canSendText] )
{
MFMessageComposeViewController * controller = [[MFMessageComposeViewController alloc] init];
controller.recipients = phones;
controller.navigationBar.tintColor = [UIColor redColor];
controller.body = body;
controller.messageComposeDelegate = self;
[self presentViewController:controller animated:YES completion:nil];
[[[[controller viewControllers] lastObject] navigationItem] setTitle:title];//修改短信界面标题
}
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"提示信息"
message:@"该设备不支持短信功能"
delegate:nil
cancelButtonTitle:@"确定"
otherButtonTitles:nil, nil];
[alert show];
}
}
参数phones：发短信的手机号码的数组，数组中是一个即单发,多个即群发。
#####4）调用发短信的方法
[self showMessageView:[NSArray arrayWithObjects:@"13888888888",@"13999999999", nil] title:@"test" body:@"你是土豪么，么么哒"];
